Intrabuilding Pathway Element
An itrabuilding pathway element is a cabling support vessel that typically connects one space to another or runs the span of a common routing cable route, but resides in one space. The format for the intrabuilding pathway element shall be fs-UUU.n.d(q) or fs1/fs2-UUU.n.d(q), where:
fs = Identifier for a space which is derived by combining the level and the building area in which the space is located. The space can be represented by the space ID (if present) or a user defined identifier (descriptor).
fs1 = Identifier for the space containing the termination of one end of the horizontal pathway, typically the most central or lowest alpha-numeric identifier
fs2 = Identifier for the space containing the termination of the other end of the horizontal pathway, typically the least central or highest alpha-numeric identifier
UUU = a user defined identifier referring to the type of element (descriptor)
n = two to four numeric characters identifying the pathway element (major ID)
d = detail information such as port, sub-duct, optical fiber and pair (minor ID)
q = qualifying information
The pathway records shall contain the following information:
•intrabuilding pathway identifier (primary indexing identifier,
e.g., 3A/3B-CT01)
•pathway type (e.g.: Cable Tray)
•pathway fill (e.g.: 20%)
•pathway loading
•cable records
•space record1 (e.g.: 3A)
•space record2 (e.g.: 3B)
•grounding record
Additional items of information desired by the system owner or operator may be added to each record, such as:
•pathway length (e.g.: 40m (132ft))
•pathway max fill (e.g.: 40%)
•pathway max load
•pathway condition
•number of bends
